代码中设置ImageView大小

主页面：

package com.xie.app;import android.app.Activity;import android.os.Bundle;import android.widget.ImageView;import android.widget.LinearLayout.LayoutParams;/** * 主页面 *  * @author Hao *  */public class MainActivity extends Activity {// 声明控件private ImageView imageView;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);// 绑定控件imageView = (ImageView) this.findViewById(R.id.imageView1);// 设置ImageView全屏显示,导包：android.widget.LinearLayout.LayoutParamsimageView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));}}

布局文件 main.xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <ImageView        android:id="@+id/imageView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/ic_launcher" /></LinearLayout>
